FHRHRY Fifth-Wheel Landing Gear Gearbox — Universal Aluminum, Black, Replace# LG-179015, OE-Fit

FHRHRY 276602 is a direct-replacement fifth-wheel landing gear gearbox designed to match OE dimensions and fit Stromberg Carlson, Lippert, Venture, Atwood and Pac-Rim landing gear systems (Replace# LG-179015 / 276602).

This aluminum universal-mount gearbox restores the drive assembly for 5th-wheel RV landing legs without modifying the existing installation. Built to OE specifications, the unit’s D-shaped input and mounting pin locations replicate factory geometry so it can be swapped in place of common OEM boxes. The housing is finished in black and is supplied with the reduction-box retainer and bolt to simplify installation.
